PR and influencer mailers are designed to do more than deliver a product.
They introduce a campaign, communicate a brand story, encourage engagement, and create an experience recipients may share with their audiences. SFL provides a camera-ready, structurally secure unboxing blank.
Single face lamination, commonly called SFL, can provide a strong foundation for PR and influencer mailers. By combining a printed paperboard surface with corrugated material, SFL can offer the high-quality graphics associated with premium presentation packaging while adding the structural support needed for parcel delivery.
This balance can help brands create mailers that arrive organized, visually polished, and ready to be opened on camera.
"PR mailers are viewed from angles retail packaging is not. Graphic layouts should cover top panels, inside lids, and sidewalls."
Camera-Ready Unboxing Experience
PR packages must look flawless when the lid lifts in front of a camera. Standard cardboard shippers look industrial, while thin folding cartons crush in transit. SFL combines a rigid fluted core with offset-printed exterior and interior paperboard sheets, allowing you to showcase hashtags, campaign messaging, or QR codes on the inside lid.
Securing the Presentation With Inserts
Multiple product samples, accessory items, and catalogs require custom interior partitions. Our dieline engineers create integrated paperboard dividers and finger notches to hold products stable during rough transit and allow recipients to lift items easily.
Handling Parcel Labels & Shippers
Shipping labels and routing barcodes can ruin premium outer graphics. We structure dedicated, clean label panels on the bottom surface of SFL mailers, or design customized outer shippers to protect the presentation-ready box inside.
PR Mailer Design Checklist

| Lid Open Sequence | Display hashtags, digital links, QR codes | Printed inside lid panels, dust flaps covering tabs |
| Product Discovery | Maintain pristine product arrangement | Nested paperboard inserts with accessible finger notches |
| Accessory Reveal | Keep secondary brochures or gifts organized | Under-tray compartments, hidden document sleeves |

Final Thoughts
"Design interior trays with liftable tabs to make products easy to remove during unboxing videos."
SFL is the ideal choice for ecommerce brands outgrowing folding cartons but needing a premium alternative to brown kraft shippers. By engineering the outer box and interior partitions as a single system, you guarantee both shipping protection and a memorable unboxing reveal.
